I have a pair of RB112 boards with Senao radio cards. I have a test setup here at the garage, two stations separated by 30m or so, power output as low as possible, bandwidth 5MHz, operating frequency 5790MHz. Each RB has its own computer attached. Bandwidth-server is enabled on both RB.
From station A, I start a Bandwidth-Test using Station B as server. RX-Current quickly comes up to 4.5Mbps, stays there for 17 seconds, then drops to zero. Stays at zero for 16 seconds then comes back to 4.5Mbps. About 17 seconds later data rate drops to 0 again. It cycles like this a number of times then finally disconnects.
From station B, I start a Bandwidth-Test to station A. RX-current comes up to 4.5Mbps and stays there for hours and hours, without any problem.
Both servers are set up identically.
[admin@MikroTik] tool bandwidth-server> print
enabled: yes
authenticate: no
allocate-udp-ports-from: 2000
max-sessions: 10
[admin@MikroTik] tool bandwidth-server>
What gives? Any wisdom would be much appreciated.

A better test is to pass traffic thru the router(s)..
IE Test unit >>>> Router1>>>> WIRELESS >>> Router2>>> Testunit..
The test server will eat your routerboard alive and spit out the CPU just for fun !!
I am local to you (I think)..
Drop me a line @ sales at pc-routers.com..
I will see what I can do to help out..

Good afternoon, Craig -
I’ve tried that too. The bandwidth-test/server function is extremely handy for setting up links without requiring computers at both ends.
Now, to your point, I’ve been using IXIA QCheck for the throughput test as well, and that doesn’t seem to work properly at all (keeps giving me a “no connectivity” error, even though I can HTTP, FTP, TELNET, PING between the computers.
Since QCheck doesn’t work, I also attempted to FTP a very large file between routers (200MB), and that should take around 400 seconds at 4.5Mbps. In the test this morning, I attempted that, and the transfer failed at about 7MB the first time and only about 1.5MB the second time. Each time the transfer rate was only 880kbps peak.
I’ll drop you a line at your other email address.
Sincerely, Jon
I have now installed the two boards in our test link to find out how well they behave. Nominally, it seems that the link can work fine.
However, now the bandwidth server/test does not appear to be able to push any traffic to measure. THe setup is as follows.
Site A
RB112
eth1 192.168.1.26/24
wlan1 10.0.1.1/30
21 km separation
Site B
RB112
eth1 192.168.2.1./24
wlan1 10.0.1.2/30
Ping, telnet, http, ftp, streaming radio, even NetMeeting works between the sites.
So, let’s say I’m at site A. I enable TOOL>BANDWIDTH-SERVER at Site B. I then enable TOOL>BANDWIDTH-TEST at Site A and the address of 192.168.2.1. The test app indicates “running” but no throughput is ever measured. Before, when the radios were 21 METERS apart, Bandwidth Serve/test worked fine, except for the issue that started this topic.
Any ideas on the bandwidth server/test does not seem to work?
Sincerely, Jon
